Description
Technical field
The utility model belongs to technical field of automobile, relates to a kind of shift fork, particularly a kind of three or four gear shift forks.
Background technique
Automotive transmission mainly refers to the gearbox of automobile, and it is divided into manual, automatic two kinds, and manual transmission, primarily of gear and axle composition, produces variable-speed torque-converting by different Gear combination; And automatic transmission case is made up of torque converter, gear transmission and hydraulic control system, reach variable-speed torque-converting by the mode of fluid power transmission and Gear combination.Function is: one, change velocity ratio; Two, in the constant situation of hand engine rotation, automobile can be fallen back traveling; Three, utilize neutral, interrupt transmission of power, to start to enable motor, idling, and be convenient to shift of transmission or carry out Power output.
A kind of automotive transmission shifting operation device (application number: 200310109909.2) disclosed in Chinese patent literature, comprise gear seat assembly and upper cap assembly two-part, wherein, gear seat assembly comprises variable speed mechanism seat, interlock board, gear shifting pulling head, block selecting axle, block selecting arm, shifting shaft and gear arm assembly, block selecting shifting block, upper cap assembly comprises upper cover, gear shift fork shaft, self-locking spring, three four-speed gear shift forks, fast fork arm, one, two-speed shifting fork, block selecting shifting block one end is fixed on block selecting axle, head is placed in the notch of gear shifting pulling head, interlock board is located in gear seat assembly, gear shifting pulling head is contained in interlock board, and be together contained on shifting shaft, interlock board top has chute, stop screw is equipped with chute, white lock spring is located in the groove of upper cover, its shape is U-shaped spring clip, leading inside is arranged with two projections, the fit depressions of gear corresponding on shifting fork, fast fork arm is furnished with corresponding spacer, gear shift fork shaft is located in self-locking spring, fix with spacing pressing plate.But this three four-speed gear shift fork is not owing to arranging wearing layer, and therefore its working life is not long.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of three or four gear shift forks had compared with the long life
The purpose of this utility model realizes by following technical proposal: three or four gear shift forks, comprise shift fork body, the end of described shift fork body has the joint of protrusion, the other end of described shift fork body is provided with two symmetrically arranged pusher dogs, it is characterized in that, the inner side of described pusher dog is provided with the butting section of protrusion, and the madial wall of described butting section has the wearing layer of curved convex body.
In use, be connected by joint declutch shift shaft, driven the axial translation of this three or four gear shift fork by declutch shift shaft.Madial wall due to butting section is provided with the wearing layer of curved convex body, therefore makes the butting section of this three or four gear shift fork not easily be worn, improves the life-span of use.
In above-mentioned 34 gear shift forks, described arc convex body is evenly arranged along the sideline of described butting section.Arc convex body is evenly arranged along the sideline of butting section, and having rational in infrastructure and arc convex body can even contact, and uniform stressed during work, improves working life.
In above-mentioned 34 gear shift forks, the middle part of described joint is provided with the attachment hole that runs through and is provided with groove of stepping down between described joint and described shift fork body.Be provided with groove of stepping down between joint and shift fork body, there is the advantage of saving material, reducing manufacture cost.
In above-mentioned 34 gear shift forks, the outer side wall of described pusher dog has spacing plane, and the spacing plane described in two is set in parallel.
In above-mentioned 34 gear shift forks, the equal fillet in edge of described pusher dog is arranged.The equal fillet in edge of pusher dog is arranged, and avoids concentrating of stress, improves working life.
In above-mentioned 34 gear shift forks, this shift fork body is forging integrative-structure.Adopt above-mentioned design, have rigidity better, pore-free and working life longer advantage.
Compared with prior art, this three or four gear shift fork has the following advantages:
1, because the madial wall of butting section is provided with the wearing layer of curved convex body, therefore make butting sections for these three or four gear shift forks not easily be worn, improve the life-span of use;
2, arc convex body is evenly arranged along the sideline of butting section, and having rational in infrastructure and arc convex body can even contact, and uniform stressed during work, improves working life;
3, the equal fillet in the edge of pusher dog is arranged, and avoids concentrating of stress, improves working life.
Accompanying drawing explanation
Fig. 1 is this three or four gear shift fork schematic front view.
Fig. 2 is that the A of Fig. 1 is to partial schematic diagram.
In figure, 1, shift fork body; 2, joint; 2a, attachment hole; 3, pusher dog; 3a, butting section; 3b, wearing layer; 3c, spacing plane; 4, to step down groove.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As illustrated in fig. 1 and 2, three or four gear shift forks, comprise shift fork body 1, the end of shift fork body 1 has the joint 2 of protrusion, the other end of shift fork body 1 is provided with two symmetrically arranged pusher dogs 3, the inner side of pusher dog 3 is provided with the butting section 3a of protrusion, and the madial wall of butting section 3a has the wearing layer 3b of curved convex body.Arc convex body is evenly arranged along the sideline of butting section 3a, and having rational in infrastructure and arc convex body can even contact, and uniform stressed during work, improves working life.
